What is it?

The term "thalassotherapy" covers a variety of treatments involving sea water and marine minerals, which were traditionally the stock-in-trade of seaside spa towns on the French coast in the 19th century.

Thalassotherapy has long been popular with actresses and film stars. Joan Collins, 72, attributes her svelte figure to standing neck-high in a saltwater pool while powerful water jets pummel various parts of her body. Jennifer Lopez is another fan.

The treatments are based on the idea that the minerals and trace elements in sea water, such as magnesium, potassium, calcium sulphates and sodium, are absorbed through the skin.

These are thought to boost the body's blood and lymph circulation, accelerating the metabolism and promoting the elimination of toxins. The jets of water pummel tension from the back and shoulders.

What are the potential benefits?

Thalassotherapy is often used purely as a detox. But it is said to be effective in treating all kinds of conditions including eczema, psoriasis, back and muscular pain, arthritis and stress. As the metabolism is improved, this can lead to weigh loss and a reduction in cellulite.

What does it involve?

A thalassotherapy treatment will begin with a chat about your health and lifestyle and any medical conditions you might wish to treat. From this, the therapist will decide a suitable programme.

Typically, this will involve immersion in a warm sea water bath while being massaged by pressurised jets. The sea water is maintained at body temperature, which is believed to allow mineral ions to pass into the blood and toxins to leave it.

This is often followed by a complementary treatment, which could be anything from a seaweed wrap to a salt scrub or mudpack facial.

Who does it?

A number of spas and larger health clubs offer thalassotherapy treatments. Expect to pay around £30 for a session. There's also a range of products that can be used at home. Thalgo is a leading brand; for details of its spa treatments call 020 7512 0872. See www.spahealthspecialists.com for details of thalassotherapy breaks abroad.

Is there proof that it works?

Yes. Athletes often use thalassotherapy to successfully treat sports injuries and French patients who suffer from arthritis are routinely prescribed water exercise, which improves their mobility.
